[0002] A spinner is a wheel-shaped deformation tool used to apply pressure to the blank during spinning. These include arc spinners, single-cone spinners, double-cone spinners, and step spinners. A conical fit is a method of connecting or securing mechanical components by fitting conical surfaces together. This fit utilizes the self-centering, large contact area, and high friction characteristics of the conical surfaces, making it widely used in many mechanical devices. The implementation of a conical fit relies on two mating conical surfaces, which can be part of gears, bearings, or other mechanical components. The fit of the conical surfaces enables functions such as force transmission and the conversion of rotational motion.

[0003] In the prior art, the assembly structure of a rotating wheel includes a shaft for driving the rotating wheel and a nut threadedly connected to the shaft. The rotating wheel is fixed to the shaft by sleeve-mounting the rotating wheel on the shaft and then threading the nut to the shaft. However, the nut connection is inefficient and requires tools to complete the nut installation and removal, resulting in low efficiency in the installation and removal of the rotating wheel.

[0032] Working principle:

[0033] The novel cone-matched rotary wheel installation structure is used when the rotary wheel 5 is sleeved on the connecting section 3, and the positioning post 4 is inserted into the positioning groove of the rotary wheel 5 to quickly complete the positioning of the rotary wheel 5. Then, the limiting plate 6 is sleeved on the outside of the rotating shaft 1, and the limiting plate 6 fits the rotary wheel 5.

[0034] The positioning pin 14 and the fixing ring 16 are moved by pulling the block 15, and the fixing ring 16 compresses the fixing spring 17, moving the guide rod 9, driving the fixing pin 12 to move, so that the fixing pin 12 is inserted into the fixing hole of the rotating shaft 1, and at the same time the guide rod 9 squeezes the supporting spring 11, releasing the pulling block 15, and the fixing spring 17 is reset, supporting the fixing ring 16, so that the positioning pin 14 is inserted into the positioning hole of the guide rod 9, fixing the positions of the guide rod 9 and the fixing pin 12, ensuring the stability of the rotating wheel 5 and the limit plate 6. Without the help of external tools, the position of the rotating wheel 5 can be fixed, and the installation of the rotating wheel 5 is completed;

[0035] When it is necessary to disassemble the rotary wheel 5, the positioning pin 14 is pulled by the pulling block 15 to separate the positioning pin 14 from the guide rod 9. Under the elastic force of the supporting spring 11, the guide rod 9 and the fixing pin 12 are pushed to move, so that the fixing pin 12 is separated from the rotating shaft 1, and the limit plate 6 and the rotary wheel 5 can be quickly removed. The rotary wheel 5 can be disassembled without the help of tools, thereby improving the disassembly and assembly efficiency of the rotary wheel 5.
